多波束深水网箱声学监测仪的研究

Study on multi-beam acoustic monitor for deep water cages

研究了一种声学监测设备,使网箱养殖者能在海水能见度较低时实现对鱼群的实时监测,进而掌握深水网箱中鱼群的生存状况。该声学监测仪由7个独立通道构成,能同时输出探测图像并通过监测仪的评估软件对数据进行分析。试验结果表明该设备能够对深水网箱中的生物量进行估计,可用于鱼类生长情况研究并监测鱼群的逃逸情况。

This paper has made study on an acoustic monitor, which enables cage cuhurists to assure real-time monitoring of fish in cages in case of poor visibility and to know the living situation of fish in cages. The acoustic monitor is made up of seven separate channels, from which detection images could be sent out and shown on screen simultaneously. The data is analyzed by software in the monitor. Results show that the monitor could make biomass estimation in the deep water cages, it also can be used to study the growth of the fish and to monitor the escape of fish.
